The Sin City star has joined the 13-episode series in a top-secret role, Marvel announced Friday, leaving fans to speculate how her unnamed character might fit into the Daredevil universe.

In fact, our only clue to Dawson’s character is in these words from Jeph Loeb, Marvel’s Head of Television: “Her role in the series is absolutely critical to Matt Murdock’s journey to become the hero we know as Daredevil.”

Dawson joins Charlie Cox, playing the show’s titular hero, and Vincent D’Onofrio, who’s been tapped to play the villainous Wilson Fisk.

Perhaps die-hard Daredevil fans can shed some light on Dawson’s top-secret role? Drop a comment with your theories about her character below.

Elektra is a Greek ninja, daughter of some diplomat. If she’s indeed her, there they go again changing something that doesn’t need to be changed and making no sense in the process. Hope she’s someone else, but no idea who it would be.

Jesus Christ on a cracker, can’t a person of color get cast in anything without some unimaginative bore making a thinly veiled racist jab at it? It’s a property based on a comic book about super heroes. They can do anything they frickin’ want and make it make sense. It’s all make-believe.

Dawson will play a “dedicated young woman whose quest to heal the wounds of Hell’s Kitchen brings Matt Murdock (Charlie Cox) unexpectedly crashing into her life” kind of sounds like Night Nurse with whole healing line.
